SEPABATOR FOR FEED WATER HEATER.

To all whom it may concern Be it known that we, JAooB M. Now, a citizen of the United States, and a resident of Collingswood, county of Camden, State of New Jersey, and FRANK JosErH MILLER, a citizen of the United States, and a resident of the city and county of Philadelphia, State of Pennsylvania, have invented an Improvement in Separators for Feed-VVater Heater, of which the following is a specification.

Our invention has referenceto separators separating the water andoil from the exhaust steam before passing into the feedwater heater or to the atmosphere; and also to reduce the amount of space necessary or permit special arrangement ofthe parts for the installation of the necessa'ryappliances which will act as a separator to the feed water heater.

Our invention consists of certain features of construction which are fully described hereinafter and more particularly defined in the claims.

The invention will be better understood by reference to the drawings, in which:

Figure 1 is a plan view of a feed-water heater with our improved separator applied theretog Fig. 2 is an elevation of the same; Fig. 3 is a plan view of the separator on a largerscale; Fig. 4 is a sectional plan view of the separator; Fig. 5 is a sectional elevation of the separator; Fig. 6 is an edge view of the separator cover with spring attach ments; and Figs. 7 to 11 are elevations of 'modifications of our invention.

2 is the feed-water heater proper and may be made in any suitable manner desired.

.3 is an exhaust pipe which leads from a steam engine or other source of steam waste;

4 is'the exhaust pipeleading to the atmosphere or to the steam heating systemas ordinarily employed but which is not shown; 5 is the separator embodying our improvements, and is located between the exhaust pipe sections 3 and 4, and 6 is the gate valve connecting the side of the separator 5 with the feed-water heater 2.

]It will be observed that the separatoris essentially a T shaped fitting, permitting, in the preferredform, the exhaust pipe sections 3 and 4 to be in exact alinement and allowing a connection with the feed-water heater through the shortest possible space, namely that occupied by the gate valve 6. This valve 6 'may be made in any suitable manner and, may correspond to valves which are now sold upon the market or maybe of any special constructionwith a view of 00- cupying less space.

Referring more specifically to theyseparator, it consists of. a body part having a lower inlet 7 and an upper outlet 8 and a lateral outlet 9. Arranged within the sepaorator and extending across the same is a steam and oil separating device 13 consisting of an upper solid plate 19, a lower perforatedplate 17 having apertures 20, and intermediate vertical .baffie plates 18,.the planes of ,whose surfaces are arranged obliquely to each other and the rear edges of which are bent or curved to form vertical gutters which preferably terminate at the bottom "adjacent to-the apertures 20 in the lower plate. The water and oil separator'device slides into guide grooves 21 and 22 within the body of the separator 5 and may be inserted 'or removed through anaperture in w the side ofthe body which is normally closed by aicover plate 24. This cover plate maybe provided with a fiat spring 25, the free ends of which maypress upon the plates 17 and 19 of the steam and oil separator deviceylS to holdit in position. In this way a loose fit may be employed without liability of rattling. The-inlet .7 isbounded-by a wall 11 and continues as'a passage 10 to the side of the separator device13 and opposite'from theoutlet 9 and by which passage the steam is fed to the separator device 13, directly opposite ;to the outlet 9 t0 the feed water heater. The space 14 between the outlet 9 and the separator device 13 extends upward and communicates with the outlet 8 which is.

connected with the exhaust pipe 4: to the atmosphere or to the pipe leading to the steam heating system in the usual way. A

transverse partition or diaphragm l2 separates the passage 10 from the outlet 8 so that the steam is required to pass between the baffle plates 18 in its passage either to the feed-water heater 2 or to the pipe 4, or to both. The body of the separator 5 is also provided with a drainage chamber 15 below the space between the outlet 9 and the separator device 13 and communicates with the under parts of the perforated plates 17 so that the water andoil separated by the baffle plates 18 run downward through the perforations 20 in the plate 17 and on the incline partition 11 from which it runs down into the said receiver or chamber 15 and from which it may be drawn through an outlet 16 with which a suitable drainage pipe 26 communicates.

It will be understood from the construction employed, that the water of condensation which may run into the separator body from the pipe 4 or which may be separated by the bafiie plates within the separator body will find its way in the chamber or receiver 15 from which it may be drawn ofi' or allowed to escape, while preventing the escape of steam. The outlet 9 adjacent to its lower part and within the body is provided with a downwardly extending oblique flange 27 which guides the steam toward the outlet and away from the chamber 15' and the water therein; and said flange may also direct any water running downward within the body and adjacent to the outlet into the chamber or receiver.

By the employment of a separator of the character described the water and oil are removed from the steam so that nothing but clean steam is delivered to the exhaust pipe or heater, and hence the use of an exhaust head on the top of the exhaust pipe is not necessary. This is also important when the exhaust steam is used for heating purposes by employment of radiators or coils. arrangement of the apparatus is such that when the gate valve 6 is opened, the direction of the flow of steam through the baffle tends to cause the steam to flow directly into the heater 2, the excess finding its way to the heating system or atmosphere by the outlet 8 andthe pipe 4:.

By providing the separator device within the body 5 in alinement with the exhaust pipes 8 and 4, there will be no loss of space required by elbow and multiplicity of connection which have heretofore been generally employed in making connection between the feed-water heater and the exhaust pipe; and moreover, the construction is exceedingly simple, easily assembled and dismantled and quickly and easily cleaned, when necessary. Furthermore, the construction is one in The which the cost is reduced to a minimum considering the results to be obtained and the machine work upon the appliance is small in amount because it is of a character which can be performed at the lowest cost. amount of metal required in the construction of the separator is also less than that which is usually employed in elbow and fittings in addition to the separator mechanism itself.

While we have shown in Figs. 1 to 5, the

preferred arrangement of inlets and outlets for our improved separator, and which would be employed where the space for the connection will permit, nevertheless, in some cases the pipe connections are such that the inlets and outlets must be varied, and as examples of these, we have shown Figs. 7 to 11, inclusive. In Fig. 7 the exhaust pipe 3 communicates with the body directly opposite the separator device 13, as if it entered the passage 10 in Fig. In Figs. 8 and 9 the construction is the same except that the exhaust pipe enters from the side most distant from the cover plate 25.

In Fig. 10 the exhaust pipe 3 enters on the side, and the outlet ports are arranged above and below. In Fig. 11 the separator is shown similarly arranged as in Fig. 7, except that there is a section of pipe between the gate valve and the side outlet of the separator. The general construction, however, of the separator in all of these modifications is the same as that shown in the preferred form, namely, in which there is one inlet and two outlets, said inlet and outlets separated by a battle device, and a diaphragm chamber opening from below the baffles.

We have shown a desired form of battle plates but it is evident that the baffle struc ture may be made in any suitable manner The '7 other than that shown; and in general, while we prefer the construction shown, the details may be modified without departing from the spirit of the invention.

Having now described our invention what we claim as new and desire to secure by Letters Patent, is:
